  • Bulk Bag Unloader Has Explosion-Protection Design

    This bulk bag unloader system is designed for use in highly contaminant-sensitive process areas handling bulk materials known to generate combustible dusts. A 9.525-mm, polycarbonate encasement surrounds the bulk bag unloader to prevent migrant dusts that piggyback on the exterior of bulk bags from...

  • Explosion-Resistant Snap-In Flexible Sleeve

    The BFM flexible sleeve assembly is a snap-in flexible sleeve that is resistant to explosion pressures. An independent study subjected the BFM assembly to designed explosive charges. Five different Seeflex materials were tested. Results conclude that the BFM assembly resists pressure shocks...

  • Portable Light-Duty Vibrator

    The magnetic mount Magnevibe is a portable light-duty vibrator. At a weight of just 4 lb, the Magnevibe is ideal for small bins and hoppers with occasional flow problems. This versatile and compact unit delivers over 40 lb of quiet force in a small 8-in. size. A ferrous, adhesive backed mounting...

  • Different Approaches to Grinding Abrasive Materials

    I have been grinding materials or particle size reduction for over 30 years. I was introduced to making powder out of lead pigs in a ball mill at my fist job, and have been working in the field of particle size reduction in one form or another for most of my life. The purpose of this article is not...

  • Explosion-Proof Rotary Airlocks

    DMN explosion-proof rotary airlocks are used in several metering and feeding applications involving powder bulk handling. Explosions due to dust are a potentially deadly and costly risk associated with any process operation that employs powders or bulk solids. Process systems and components often...

  • Vibratory Feeders Designed for Tough Jobs

    These vibratory feeders are designed to smoothly convey products. Flow of material is adjustable, and flow rate can be variable or fixed.        Available in electric or air-operated models, BPS heavy-duty vibratory feeders are designed with above-, below-, or side-mounted...

  • How Material Size Directly Affects Size Reduction Energy

    This is a study of how the size of the starting material can influence the processing rate, tightness of the particle size distribution, and energy costs associated with particle size reduction.     There are many reasons to pursue jet milling as part of your size reduction plan....

  • Growing Nutraceutical Market – Shrinking Particle Sizes

    Nutritional supplements have begun exiting the shadows of the vitamins market to become their own unique market segment. Nutritional supplements, such as those taken by health conscious work-out enthusiasts, take several forms like drink mixes, capsules, tablets, and gels. And the old, gold-...

  • Combustible Dust: It’s Explosive

    The top four reasons people are concerned about combustible dust include: 1. health and safety of employees; 2. fear of a potential OSHA inspection; 3. already had an OSHA inspection; and 4. the possibility of an explosion. All these are valid and legitimate concerns.     It is...

  • Should You Use Nitrogen for Your Size Reduction Operation?

    By Tim Boland, Air Products Size reduction of solid materials is one of the most important technologies in the modern world because of the breadth of products it impacts. While size reduction is a widely practiced technology, it is not a particularly energy-efficient process. It has been estimated...
